NORMAN, Okla. (AP) Baker Mayfield began the week with tears and an apology.

He ended it as he so often has - by celebrating a victory.

The Oklahoma quarterback passed for 281 yards and three touchdowns after being punished for directing a lewd gesture toward the Kansas bench last week, and the third-ranked Sooners routed West Virginia 59-31 on Saturday to maintain their momentum heading into the Big 12 Championship game.
